As I recall injection pump volume is between 0.0x and 0.00X CC per cycle = this is why it takes seriously extended cranking when you totally run out of fuel..

The only other answer is the braided fuel bypass hose, from injector #1 to the fuel filter was stuck into the injector hole for weeks.
If the fuel tank vent valve is bad/plugged = This would cause an issue called breathing:
* Daily Heat expansion would flow diesel into cylinder #1.
* Nightly cooling would suck air back into the tank..
* A variation of 10° F (or more) between night and day is all that is needed, the wider the temperature difference = more fuel transfer...
Easy to test = remove the fuel cap and listen for pressure escaping..
